ISO 17564:2008 specifies a method using Wijs' solution to determine the iodine value (i.e. the residual unsaturation) of raw hydrogenated nitrile rubber (HNBR).
Abstract
Overview
ISO 17564:2008 is an international standard developed by the International Organization for Standardization (ISO) that specifies a reliable analytical method for determining the residual unsaturation in raw hydrogenated nitrile rubber (HNBR). This is achieved by measuring the iodine value, which quantifies the degree of unsaturation present in the rubber sample. The method utilizes , a halogen reagent, to react with the double bonds in the polymer chain. Accurate measurement of residual unsaturation is critical for quality control and performance assessment of HNBR materials used in various industrial applications.
